Application filed April 1, 1912.

To l W/l m/ if mr/ concern Be it known that l, itxmacw lioennmn, a suhject oi the King of lingland. residing at San l"'rancisc in the count of San Francisco and State ot Cali'l'ornia. have inrcnted certain new ,and llhtl lll Improvetnents in Door-Secur rs oi which the following is a speeitieat on, re'li'erence being had to the accootpanyingr drawings.

This invention rclatea generally to builders' hardware and more particularlv to door se urers the intention having! for its pri lluil' V ohject a siinplc and etlieientconstruction of device which may he conveniently applied to the latch keeper of a door and when in opcratire position held the door securely closed and prevented from adding.

-'lhe invention also has or its ohject a device ol his character which will he Secure and 'p sitite in its action to prevent the uinuithorized opening ol the door. and which may he ttl ll carried ahout the person or in a hand liar. wherehy a traveler for instance may always have at hand ineans l'or securelr locking the door ot his room in case the door itsell' i.-: not prorided with a bolt or other 'l'orin ol l A still further olr-jectot the invention a device ol' this chara ter the parts: of which may he easil) untnut'acturcd and readily asse ultletl and the in\ention also aims to genera ly iinprore this class at ltltlis and to render tl cin more useful and coinlnercialli desirable.

With these and other objects in View as: will more l'ully appear asthe t lescription proceeds. the intention consists in certain constructions. arrangements and eomhinatious' ol' the parts tha .l shall hereinatter l'ull t lescrihe and claiin.

For a full nnderstandiue oi the invention reference is to he had to the following description and accompanying drawings, in which r l igure l is a horizontalsectional view through a door 'asing and door. illustratrich.

My ilnprored deer latch or lock includes a liar l which is f rmed n ar one endwith a bend 9 which d "Jned to be inserted in the latch keeper of a ml easing, as clearly illustrated in Fig. l. The lfill' l is formed with a laterall; reduced ion 3, one end of said extenaion Ciel}.

The har l formed with shoulders t here the extension l ins and the said extension is fOt'lilLti in en. side of itsangular portion with a longitudinally extending groore T which terminates at one end in a transverse recess In and at its other end in a shoulder 9, as clear illustrated in Fig. l.

it) designates the harrel of the locking; derice. 'lh barrel is formed at. one end with laterally stacet'i arr: llwhich straddle the angular extension 3 at the bar 1, a pin or rivet ti? extending through the ends of th a'rins ill so as to hold the liarrel on the extension l) for a longitudinal sliding movement thereon. The l arrel 10 is pro- \"ided at one end with a prete 'alily rubber plug l3 which designed it) directly engage the outer face of the door as clearly illustrated in Fig. l, whereln' to prerent inarring orotherwise injuring); the linish ot' the door.

The r air or outer end ol the barrel 10 is .lortned with an interior the. 1t designed to detaehahlr retain a lit) lit in proper relation to the harrel. For till-s purpose. the key 15 is formed at one end with a hit it"), said hit being, formed with. a longitudinal groove lT terminating at its inner end in spiral recess 18, bounded on one side by 1 Spiral cant 19 which is intersected by longitudinal slot 20. To enter the loit 16 into the end oi? the barrel 10. the barrel is first slipped orer the angular extension 3 of the bar 1 and held. at the point where the two angular portions of the extension'ineet, and the hit 10 is then slipped into the rear or outer end of the arrel, the groove 17 registering with the l e ll. 'Wl en this inward inoreinent causes tl e lug: it to register with the slot or transverse spiral recess 13, thekey is given a partial rotation in a eloclewise direction,which will cause the lug to ride in the spiral recess 18 and therp-h v detachahly connect the key to the barrel. 175v forming the key 15 with a longit'mlinal slot 20 intersecting" the cam 19, the key and barrel may be easily slid along the extension I} oi the bar 1 to the inoperative position illinti'a'tcd in dotted lines in fig. 1, thccntirc removal or detachment of the ltev and valve being prevented by the rain abnnine'aeai11st the ehonlder i). in the operative position of the key and barrel, ilho-trated in lull lines in Fig. 1, the cam l9 re liters with the i'12i11:-1\'t}i$0 recess 8.

From the foregoing description in connec tion with the accompanying drawing the ol'ioratioi'i of in improved door locking device 11 ill be apparent. in the practical use of the device the bend, i? of the bar 1 is insorted in the latch keeper of the door casing and the barrel and licv -are backed oil to tho p11.- iti11n illu:- tratcd in dot-ted lines in l"i; i. it.

l'fhile the accompanying drawing illus-- irate .what i believe to be the prel crrml e111- hodiinent of my invention, it is to be understood that the invention is not (limited thereto but that; varioim cllnligcs may be made in the raiinrrncii in arrangement and pro-- portion oif thepartn without departing from the woope of the invention as defined in the appendix] ctaiins.
